1. ZN63 VS1 series 3 phase indoor vcb vacuum circuit breaker 6.6kv 7.2kv 10kv 20kv 24kv
ZN63 series vacuum circuit breaker is three-phase AC 50Hz indoor
high voltage switchgear with the voltage of 7.2~15kV, it is used to
control and protect electric utilities in industrial and mining
enterprises, power stations and substations. Based on more than ten
years of extensive experience in design and manufacture of vacuum
circuit breaker, we introduce a new generation of high performance
product in the twenty-first century.It complies with the
requirement of GB1984,DL403 and IEC56 standards and so on.
ZN63A-12/T1250-31.5 vacuum circuit breaker passed the type test in KEMA International Electric Experimental Station in Holland.
